It appears that one of the Nether passages has been recently blocked. Just curious if anyone knows why.

Previously, if you stepped out of the Spawn portal and turned left, you'd pass the intersection which takes you to Obsi's and Aveege's on the left (shown in translucent gray), down a step, past the Cactus pillars with the sign pointing to TOUR0KS Estate and Blacksok's Mound on the right (via walk or rail track), then down a short flight of stairs. Previously, at the bottom of the stairs was a passage to the left, that offered a U turn and then down a couple flights of stairs and eventually ended up in the old Spawn portal room, beside Admiral Trigger Happy's Nether Farm. But as shown in the diagram below, there is now a wall at the translucent orange rectangle, and though there are some remains of the red stairs, they have largely been blocked by the added wall.
